“We need to avoid the situation in the Netherlands where one faction wants to save nature and the other to introduce renewables. If you don’t bring them together it will be disastrous.” EWEA Vice-President Jos Beurskens, 2001
Uncertainties – the main ones! • Birds – displacement, barrier effect collisions • Fish – electromagnetic effects; change in fishing effort • Marine mammals – underwater noise • Seascape – how evaluate, layout? • Cumulative assessments – how?
Sharks, skates and rays • Will windfarm cables affect behaviour or populations? • Many species depleted in UK waters • Use inshore sandbanks for feeding, breeding, nursery areas • Lab tests show avoidance and attraction • Shielding and burial of cables
Stages of assessment Delineate seascape unit Visual analysis Describe - marine, coastline, hinterland Identify seascape character Evaluate – quality, value, capacity
Dynamism and variability Scale and distance Different sea to land/land to sea Visual movement Historic and cultural aspects Functions and uses
Visibility of Sea from Land Visibility = number of 1 km points visible from every 50 m pixel ONLY derived from points on land Sample points
Existing offshore activities located in Liverpool Bay showing site of proposed wind farms
